Standard

— For standard 1.33 inputs (also known as full screen).

Anamorphic

— Provides vertical image squeezing to accommodate

anamorphically enhanced DVDs (1.85).

Wide screen

— For wide 1.78 inputs (letterbox).

Wider screen

Tomarama

— Expands a 16:9 signal to fill a 4:3 screen (1.78). As it expands

Most VCRs and satellite receivers output a signal with a 4:3 aspect ratio. How this
signal is filled with video determines its aspect ratio. Figure 3-10 shows four
examples of different input aspect ratios in their native 4:3 format and as they
appear after scaling.
